The only part lacking
The only part lacking was the plot, which was dull to watch, and I think the ending was very confusing. I didn't care at all about the history, and it was all very recognizable and very well done, but maybe I was just too stupid to care.
The only part lacking is the fact that ultimately this film is just plain bad. Like a bad Oscar-nominated film from the 70's, the acting is awful and the jokes are lame. In fact, the only reason I have seen this film is that it was made for TV in the 70's, and it's a shame that this film failed.
